Application filed May 6, 1915. Serial No. 26,383.

To all. whom t may concern): Y

Be it known that I, EDWARD F. TALLEY, a citizen of the United States,residing at Webb City, in the county of'Jasper. and State of Missouri',have invented certain new and usefiil Improvements in Grade-.CrossingGates, of which the following a 'specification. i' I "5. f Thisinvention relates to gates and more particularly relates to agradeycrossing gate adap'tedto be automaticallyv operated bythe approach andpassage -ofa train, in order to preventtravelers from 'attempting `tocross thetrack..`. M

As a principal object, it is contemplated by this. invention to providea vertically swinging. gate by the V'side of the grade crossing andtoprovidein association therewith Suitable track trips whereby movement ofthe gate may be automatically:controlled by the passagelof a train.. 1,'

.A further object is to provide a casing for housing the operatingmechanism Jfor the gate in @device ofthis character-,such casing beingslottedv to limitmovem'ent. of the gate and such 4mechanism includingspring means for returning the gate to 'its normal position while thetrain ispassing4 the cross- 111g... .5. It. is a more specific objectto'pivot a gate within a casing,ffor vertical movement, to attach a segmentto` suchgate, toprovide Aa spring pressedlocking ,bolt normally main'-taining the gate iii its raisedposition, to associate track trip meansVwithsaid `locking bolt in such manner thatapproachoi', a train willreleasesaid .bolt and permit said gate to assume its'closed positionfandto associate a second .track trip withspringlme'ans so that passageof the train will causethe spring to coact with. said segmentin.returning `said gate to itsnormallocked position. f i

The. above and; additional objects which will become app-arent.. as thisexplanatory description. .pro`ceeds,'are accomplished by such `meansasare illustrated inthe accom: panying ',drawings, .described.inY thefollowing specification.andthen .more particularly Lpoi'nte'cljcmt the.Lclfairs :which .arev Lap.- pendedhere o. and .formapart of thisappli..- caIl'.. -.With rete renceztoQtlie .dawinga wherein there?. is.illustrated the.y preferrediembodi nient.ofthiaimpmionc as; tiaducedLto practiceaid throughout the several vviews of which like charactersof reference designate similar parts:

In the assembled view of Fig. 1, there is illustrated a grade-crossing,as the term is applied to the intersection oi a public road or street,-with a railway track. rlhis latter is designated 10 'and includes railsmounted upon the usual cross ties 11 which Support track trip casings 1Qand 13, the-latter being positioned at one side of thctrack directlyopposite a gate casing 14e while the' former are placed along thc trackat such distances from the casing 14 as'to furnish ample time for thearm to be operated thereby uponthe approach of a train.

' Upon reference to Figs. 2, 3 and 4 which illustrate thc casing 14 indctail,-it willbe seen that such casing is Aprovided with the arcuatet'op 16 which is formed'V with a-slot public road or grade-crossing, bythe side of which the casing 14 is positioned. Upon that portion of thearm 18 within the casing 14 there is secured the channeled segment 2Owhich serves as a guide for the spring ribbon 21 which is received uponthe segment 2O from a spiral coil 22 mounted upon the transverse axle 28within the casing. The free extremity of this spring ribbon engages inthe manner denoted by the numeral 24 with a hook member 25 which isformed on opposite sides with the hook portions 2G and 27, this lattercarrying an eyelet 28 for the engagement tlier'e\\ith of a flexibleconnection. ln F ig. 4 l have illustrated a modified form of myinvention and in this instance the casing has mounted therein the doublesegment 20 which consists of portions7 each equivalent to the segment ofFig. 8 and mounted upon opposite sides of the arm 18. By the use of thisadditional segment the spring ribbons 2l accommodated therein arerendered more positive and balanced in their action upon the arm.

rlThe locking means maintaining the gate 18 normally in raised positionis illustrated in detail in Fig. 8 and will be seen to include separatecasings 29 and() which are respectively carried by the gate 18 and bythe housing 14 in juxtaposition to the upper terminus of the slot 17. lneach of these casings there is slidable a bolt 81 which bolt is normallymaintained in the position illustrated in this figure by coil springEach of these bolts is formed with an angular extremity 88 so that theymay readily engage for longitudinal Vmovement without the slightestinterference with the vertical swinging movement of the gate about itspivot 19. The bolt 81 carried by the swinging arm is provided with anelongation 34 which projects through the arm and into the channeledportion of the segment 20 unless withdrawn therefrom by a releasing pullfrom the other bolt 81, this latter having its extremity formed with aneye 35 for engagement with an operating flexible connection. A keeper 88is secured to the arcuate top of the housing as indicated in Fig. and isadapted to normally engage the catch member 26 of the spring carriedhook 25, as will be later more completely set forth in the discussion ofthe operation of this safety appliance.

Considering now the track trips adapted to operate the gate 18 throughthe housed mechanism just described, it will be apparent that these mayassume either of the forms illustrated in Figs. 5 and 6, or F ig. 7. lnthe first mentioned figures the trip disclosed includes a base casting87 which is supported upon the ties 11 adjacent the track 10. A. bearingcap 88 is secured to the base casting and a partially rotatable shaft 89is mounted therein and projected toward the track 10. Secured to thisshaft is the trip arm 40 the upper portion 41 of which Vis hinged bymeans 42, although normally alined with the lower portion by the leafspring 43. This upper portion is adapted to be contacted with by a rodor similar device 44 which may project from the pilot or other suitablepoint of the engine designated 45, while the lower portion of the trip40 has connected thereto the flexible control 46, the movement of whichin one direction is limited by a stop 47 carried by the base casting.

The modified form of track trip illustrated in Fig. 7 includes thehollow casting 48 which may be positioned upon the ties 11 as previouslydescribed and in which is journaled the verticall shaft 49. The upperend of the shaft is extended upwardly from the casing 48 and isflattened upon its upper extremity the flattened portion being providedwith a series of adjusting apertures 50 which variably receive the boltor set screw 51 in maintaining the operating bar 52 in the desiredadjusted position. At its lower extremity the shaft 49 carries a pulley58 over kwhich is trained and to which is secured the flexibleconnection 46 extending into the casing and which is given an actuatingmovement substantially the same as by the first described trippingmechanism. A spring' 54 is coiled around the shaft 49 and has one endanchored in the casing 48 in order to return the shaft to that positionWhere the arm 52 extends at right angles to the track 10.

1t will bejunderstood that a pair of the track trips 12 are situatedadjacent the track 10 and at opposite equal distances from the casing 14toward which both of the flexible controls 45 from these trips 12 run,entering the casing to a common connection 55 after passing over a pairof pulleys 56 separately mounted upon simil ar supports 57. Continuingfrom the common connection 55 this double control 58 extends upwardlyfor engagement with the eye 35 of the operating bolt 31. Similarly aflexible connection 59 extends from the eye 28 carried by the hookmember over the pulley 60 and transversely out of the casing 14 for anysuitable engagement such as those already described in similarconnections with the arm 61 mounted upon the track casing 18. The arm 61is preferably pivotally mounted with respect to the casing 13. rlheflexible connection 59 may pass in any suitable manner beneath the ties11 and the track rails 10 to the casing 13. The end of this flexiblemember is then connected in a suitable manner so as to have coperativeaction with the arm 61. The arm 6l is preferably so posi tioned that itwill serve to operate the tripping mechanism upon the in either'direction.'

passage of a train y In a reduction to practice, it will be obvious thatthe gate 18 may carry the sign board 62 having any suitable signal orwarning legend thereon and may also be equipped with the illuminatingmeans 63 freely mounted at the extremity of the bracket arm 64 so thateither position of the gate 1S will permit the lamp 63 to occupy thenecessary vertical position. Considering that the arm is in its verticalposition and that the train L15 is approaching the grade-crossing in theindicated direction it will be seen that the trip 44 engaging with thegate 41 of the track trip 12 at the right of Fig. 1 will exert a pullupon the flexible control 16 which will withdraw the bolt portion 34from the channel of the segment 20. This bolt portion is normallyengaged by the hook 27 of the member 25, as will be obvious from aninspection of this portion of Fig. 2, so that the resistance of thespring 22 prevents the force of gravity upon the extended end of thegate 18 from permitting this gate to fall into its horizontal position.The withdrawal of the bolt 34 however disengages the gate from theaction of the spring and causes the gate to close the highway againsttraffic. When the train has reached the trip 13, the arm 61 will beactuated thereby to exert a pull upon the flexible control 59 which willbe so arranged as to be sufficient to pull the spring ribbon 21forwardly in the channel segment until the hook 27 again engages withthe bolt portion 34. The spring 22 having been thus called upon to exertits action upon the arm 18, the latter will be lifted to its normalvertical position, the hook 26 engaging the keeper 36 which preventsbackward slipping oi' the spring ribbon when the gate is let down.Incidentally the hook ends 33 engage each other so as to allowsubsequent operation.

While in the foregoing, however, there has thus been illustrated in thedrawings and described in the specification such combination andarrangement of elements as constitute the preferred embodiment of thisinvention, it is desired to emphasize the fact that such minor changesin the matters of proportion and degree may be made in later adaptationsof this device as shall not alter the spirit of the invention as definedin the appended claims.
